Github user zhangminglei commented on the issue: https://github.com/apache/flink/pull/4168 Thanks @twalthr for reporting this VERY good issue. And thanks @zentol for looking over it. PR has been updated. I misread the error from JIRA before , so literally used ```trim()``` to solve and it was proved to be wrong.
